“She didn’t like to be alone. Even more, she didn’t like being with people.” ― Elizabeth Strout, from the novel Olive Kitteridge
Dependency is the cainist’s bugaboo. He lives in a fantasy world where he’s special to a fault and the Enabler has no value. Yet, he’s dependent on the her to obtain admiration and attention, to pilfer her thoughts and ideas, and to use her as a model or prototype on how to act in public. A sympathetic Enabler has saved a haughty cainist from the gallows more than once. He knows this and loathes it.
His selfishness wears thin over time. One study showed that cainists became unpopular after 7 weeks or after approximately 2.5 hours of contact time. [i] However, that doesn’t stop him from exploiting, devaluing and discarding the Enabler when she is no further use to him.
A cainist will use an Enabler to put him through college, then ditch her when he lands a lucrative job. One cainist, who had trouble keeping a job, remains with an Enabler because she brings home the paycheck, then boasts to everyone that he only has to work part-time and loves it.
There’s little, if any, loyalty from him. Once he’s convinced that he’s too exceptional to remain with a minion, he quickly, and often abruptly, moves on. In romantic affairs, he usually lands someone new before he leaves the previous Enabler because he hates being alone. He’s like a vulture, picking at a carcass for the last remnants, then ditching it when there’s no meat left on the bones.
